My invention relates yto a new and useful improvement in a furnace adapted particuf larly for use for heating purposes and especia'lly a Vfurnace used for generating steam whetherused for heating or power purposes,

the presentinvention being an improvementV on my invention set out in my application for-Letters-LPatent.Serial No. 167 ,409, filed February 11, 1927. v f

`It is an iobject of thepresent inventiontin addition to attaining the objects attained by the original'invention, rset out in the application referred-to, to provide'A an upper ksection whereby the lcommunieation of the inner- 'positioned sections with the 'outer sections may be eifected'at other points than directly opposite the outlet ope'ning of the steam dome. ff j* It is another object of the invention to provide a steam furnace of this' class in which the steam may be led therefrom without an excess of moisture from the furnace with the steam. Other objects will appear' hereinafter. rlhe invention consistsin the combination and arrangement lof parts hereinafter described and claimed. Y y. v The invention will be best understood by'a reference to the, accompanying drawings, which form a part of this specification and in which, j

Fig. 1 is a central vertical sectional view in fragment of a' furnace embodying ythe invention. l

Fig. 2 is av section-al view taken `on lline 2-2 of Fig. 1. v l

Fig. 3 is a fragmentary sectional view cf the structure shown in Fig. 1 taken on the line indicated bythe section line of Fig.2. Y ,Y

Theinvention primarily relates to the` inner positioned section directly beneath the steam dome ,and to illustrate theuse of the invention I .have shown inthe drawings'v a furnace embodying a base 9., projecting up7 wardly' from which is a supporting drum 10 having an opening 11 formedv in the for-` ward side thereofanol closed by a suitable doorr127 havingI a Vsmaller door- -13 hingedly vmounted thereon, as fa closure forthe Vair vent` opening 14. Proj ecting inwardly from 15, on the upper surface of which is the bead A16, which engages ina groove-17 formed in the supporting section ofthe fur-k I naceA positioned thereon'.v As shown in the Vfrom 'an outer wall 18 andan inner wall `19,s pace'd therefrom. Formed integral with 60. thereof is a globe shaped containerp20 which Y Y the vinner wall 19 and projecting inwardly is provided with the upwardly-projecting,

ginterior'ly threaded' neck 21 in' vwhich is threaded a nipple or pipe section22 which .alsofthreads into the neck 23 of theflatdisclike lhollow section or member12li serving lto bindtheV section or memberV 24 on the'container Y2O. f An upwardly' projecting neck 25 is formed'on this section `or member 24,.

tand connected bythe nippleor pipe section y26 to the downwardly projecting neck a'fnipple or pipe'section 29 which vthreads into an' opening 30 formed in the base 31 off a section comprising the outer` wall '32 and an inner wall 33 which is bulged inwardly' to form the inwardly directed hollow, cornl parlativelyshallow container 34' and to form,

with the disc-like sections, sinuous passages for the escape of gas Threaded into the` opening` 35 formed :in the upper wall 36 offthisvsection` is a nippleor pipesection positioned thereon, this section being a du-V rtheupper edge-'lof this r'door 12 isl a iiange. .5

vdrawing,y Vthis supportingsection-is formed v23` on thedisclike tubular sectionor'memaber positioned thereabove, .the succeeding ,structure-being but a duplication `ofthese parts, :Threaded intoan opening27 formed' r inthetop 28 lof the supporting section is 537 which serves to bind thereto the section l y lized may be varied, although in the structure illustrated I prefer to use three.

The invention comprises 1n combination with the structure shown the u oermost centrally positioned or disc-'like section, this section forming the hollow container 88 having the downwardly directed neck 39 which is interiorly threaded for the reception ot the nipple or threaded pipe section 40 which serves to bindthis container 38 in communication with the centrally positioned or disc-like sections below. An upwardly projecting neck 4l is interiorly threaded tor the reception oi one end 'ot the pipe section 42, the other end of which projects through the opening in the dome 43 and is retained in position therein by the jam nut 44 and the packing 45. Formed in the lower wall 46 of this containerBS are a plurality of openings 47. Threaded into these openings 47 are nipples orpipe sections 48, which serve to bind the lower wall 46 to the outer section positioned therebelow. A vsimilar nipple or pipe section 49 is threaded into an opening formed in the top wall 50 and into an opening formed in the base of the dome 43. In the structure` shown, I have provided three sets of these openings so that the container 38 comprises a central main body portion communicating through passages 51 with the space 52and through the openings 49 with the `lowermost section and the dome 43. It will be noted in Fig. 2 that the walls 53 and 54 which define the space or chamber 52,'do not extend Yaround the container 38 completely but terminate at the forward side of the boiler to provide a cleanout space 55 which is normally closed by the door 56;

By connecting the central positioned sections through the container 88 with the in terior of the outer sections, the water level may be maintained at a point below the upper wall 5G of the container 38 and when this water is heated so that boiling or bubbling will take effect in the innermost sections, on account of the communication with the outer sections, a forcing ofthe water through the pipe section 42 will be prevented, thus assuring a drier steam than would be 4the case were the container'o to be replaced with one of the lower positioned central sections.

The upper section or container 3S may, from the description given, be properly described as a section having a central circular portion surrounded by and communicating' with a circular tubular ring portion, this ring portion communicating through openings with the outer section.

While I have illustratedv and 'described the preferred form of my` invention',` I do not wish to limit myself to the precise detailsof structure shown, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

l. A furnace ot the class described, comprising: a plurality of duplicate double walled sections, with the spaces between said walls in intercommunication, the inner wall oi' each of said sections being bulged inwardly away Jfrom the outer wall, a plurality ot centrally disposed discnlike hollow intercommunicating members enclosed by saidrdouble walled sections, the edges of adjacent discflike members extending in overlapping spaced relation to said bulged walls, thespace between said bulged walls and said disc-like members forming sinuous passages for the escape of gas, a supporting section comprising spaced walls from continuations of the walls of the double walled sections, the space between said walls being in communication with the space between said double walled sections, a centrally disposed hollow globe shaped container connected to said supporting section and said disc-like members and establishing communication between the enclosed spaces of said sections and members and providing support :tor said disc-like members, atop disc-like section in intercommunication with said disc-like member, a ring partially embracing said top disc-like section and communicating therewith and resting upon and communicating with the uppermost of said double walled sections, a hollow top section communicating with said top disc-like section and with said double walled sections, and having an exit flue in communication with said sinuous passages said supporting section enclosing a combustion chamber space.-

2. A furnace of the class described, com* prising: a plurality of duplicate double walled sections, with the spaces between said walls in intercommunication, the inner wallV of each of said sections beingbulged inwardly away from the outer wall, a plurality of centrally disposed disc-like hollow intercommunicating members enclosed by said double walled sections, the edges of adjacent disc-lille members extending in overlapping spaced relation to said bulged walls, the space between said bulged walls and said disc-like members forming sinuous passages for the escape of gas, a supporting section comprising spaced walls from continuations of the walls of the double walled sections, the space between said walls being in communicationl withr the space between said doubled walled sections, a centrally disposed hollow globe shaped container connected to said supporting section and said 'disc-like' members and establishing communication between the enclosed spaces of said sections and members and providing support for said dise-like members, a top `disoelike hollow section communicating at its central portion with said dso-lkemembers and havinge hollow portion overlying the uppermost of saddouhle walled sections and oom.-

municatng therewith, a hollow top section communicating with said topdiso-like seo'- tion and having an eXt Hue in communica.-V
